At the end of the forest road, there is an observatory where you can see Tomogashima and the Kitan Strait.
On a clear day, you can see the Akashi Kaikyo Bridge and Shikoku, and it is also known as a scenic spot for the sunset.

The Meiji government, recognizing the importance of the Kitan Strait, set up Western-style gun batteries in the Naruto and Yura districts of Awaji Island, and in the Tomogashima and Kada districts of Wakayama City.
The Imperial Army fortified the area in anticipation of an attack by the Chinese Navy during the Sino-Japanese War and by the Russian Baltic Fleet during the Russo-Japanese War.

瀬戸内海国立公園の指定特別地域
深山砲台跡は、友ヶ島地区、淡路島の由良地区の砲台とともに明治時代に築かれた由良要塞の一部で、大阪湾を防衛する役割を担っていた施設です。
林道を抜けた先には、友ヶ島や紀淡海峡が一望できる展望台があります。
天気の良い日には、明石海峡大橋や四国まで見渡すことができ、夕日の絶景スポットとしても知られています。

紀淡海峡の重要性を認識していた明治政府は、淡路島の鳴門・由良地区、和歌山市側の友ヶ島・加太地区に洋式の砲台を構えました。日清戦争時には中国の清国海軍、日露戦争時にはロシアのバルチック艦隊の襲来を念頭に、帝国陸軍が一帯を要塞化しました。（明治22年由良要塞の建設を開始）。

深山砲台（第1砲台）は、加太南部の田倉崎砲台（現在の和歌山市立青少年国際交流センター一帯）とともに本土側に設置された砲台で、北西方向の砲撃を任務としました。
日清戦争後（日清講和条約は明治28年調印）の明治30年に竣工し、（日露戦争は明治37年開戦）深山要塞跡（第一砲台跡）として深山要塞跡（第二砲台跡）、深山要塞跡（男良谷砲台跡）とともに和歌山市の文化財に指定されています。

紀淡海峡を一望にする深山第一砲台には、観測所や6門のドイツ製28cm榴弾砲（りゅうだんほう）が設置され、今もその基部、弾薬庫跡などの遺構が残っています。
さらに歩けば友ヶ島が見える展望台もあります。
明治26年竣工の深山第二砲台は、終戦後に爆破され、施設のほとんどは消滅し、現在は国立公園内に建つリゾートホテル「休暇村紀州加太」の本館の敷地になっていて、ロビーなどからその圧倒的な景観が見渡せます（敷地内に弾薬庫や砲具庫として使用されたと推測される地下式掩蔽部が1基のみ現存）。
